HEADLIGHT.

assess.

To all whom it may concern:

.Be it known that I, EIIIR'LAM B. POOLE,

a citizen of the United States. residing at Delmar, in the county of \Vinston, State of i-\labama, have invented certain new and useful Improvements in Headlights; and I do hereby declare the following to he a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to locomotives and has special reference to headlights for locomotives.

One object of the invention is to provide an improved form of headlight tor locomotives in which the beam of light is constantly directed on the track no matter whether the locomotive be running on a tangent 0r curve.

Another object of the invention is to pr0- vide a device of this character connected irect-ly to the front axle of a locomotive so that as this axle swings the beam of light will be kept constantly at right angles there to.

\Vith the above and other objects in view the invention consists in general of a rotatably supported headlight and an improved connection betwcen the support and the front axle of a locomotive.

The invention further consists in certain novel details oi construction and combina tions of'parts hereinafter fully described, illustrated in the accompanying drawings, and specifically set forth in the claim.

In the accompanying drawings, like characters of reference indicate like parts in the several views, nth-Figure 1 is a front elevation of an engine arranged in record ance with this invention showing the device ap lied. Fig. 2 is a top plan ax e and the device removed. Fig. 3 is a detail view of one of the forks and its connection with the axle.

The numeral 10 indicates the front sheet or smoke-box door of an engine and at 11 is disclosed the front axle of an engine which may be either the axle of a bogie truck or the front axle of a four wheeled leading truck. Mounted upon the door 10 is a Specification of Letters Patent.

bracket 12 provided with a vertical perforation extending therethrough and through this bracket runs a shaft 13 provided with an enlarged head 14. whereon is mounted a piatforin 15 arranged to receive and held a headlight 1.6. In order to retain the shaft 13 in its proper position within. the bracketthis shaft is provided on each side of the bracket with collars 17 which are pinned or otherwise attached thereto so that the shaft is held from longitudinal movement in the bracket. is a yoke 18 comprising a pair of outwardly extending arms downwardly curved at their extremities. The center lines of the shaft 13, yoke 18 and axle 11 all lie in the same plane, the shaft thus being directly over the center of the axle when. the engine is traveling on a tangent. Upon the end of each yoke arm is a fork 19 the arms of which extend over the axlell in spaced relation thereto and these fork arnis further have their lower extremities parallelto act as guides for bushings 2O surrounding the axle 11 and provided with flanges between which the arms of the forks l9 engage so that the bushing are allowed to move up and down in the forks as the axle 11 moves up and down in its hearings. This construction makes provision for the constantly varying distance due to the inequalities of the track between the center line of the boiler and the front truck.

By means of this arrangement when the engine strikes a curve the front axle 11 is swung to one side to follow the curve and this causes the yoke 1.8 to swing snhstantially in unison therewith thus rotating the shaft 13 and causing the loci in of light from the headlight 16 to he constantly directed along the track.

It will he noted that this device is simple in construction, of few parts and readily constructed and that there has thus been provided a. novel and efiicient device of the kind described and for the purpose specified.

Having thus described the invention, what is claimed as new, is zln a device of the kind described, the coin bination with an engine and its front axle; of a bracket fixed on the engine, a shaft ro Upon the lower end of this shaft tatably mounted in the bracket, a headlight In testimony whereof, I afilx my signaplatform fixed on said shaft, a yoke at ture, in presence of two witnesses. tached to the lower end of said shaft, forks at the ends of said yoke engaged over said EPHRIAM POOLE 5 axle, and bushing onsaid axle and held in W itnesses:
